How to distinguish between the pin diagram of the infrared receiver

The infrared receiver generally has three pins, including power supply pins(VCC), grounding(GND) and signal output pins(OUT or IR). To determine the pin of the ir receiver, the following methods can be used:

1. The pin of the conventional MYS IR receiver is judged: The person is facing the receiving surface of the infrared receiver (the receiving surface has obvious spherical convex, generally spherical or nose bridge shape), the middle foot is the grounding pins(GND), the left is the signal output pins(OUT or IR), and the right is the power supply pins(VCC)
2. Through the product specification: In the specification of the IR receiver, there is usually a product size diagram, which can be used to determine the pin of the IR receiver.
